  • Publication number: 20240103470
    Abstract: An information processing apparatus that updates a regression coefficient parameter based on a predetermined objective function including a regularization term for each of a plurality of elements characterized by a task and a feature value, the information processing apparatus comprising processing circuitry. The processing circuitry selects an element which is an update target of the regression coefficient parameter from the plurality of elements, fixes a value of the regularization term of an unselected element, selects a calculation expression for updating a regression coefficient parameter of the selected element based on a regression coefficient parameter of the unselected element, and updates the regression coefficient parameter of the selected element based on the selected calculation expression.

  • Publication number: 20080014510
    Abstract: A photomask designing apparatus designs a photomask provided with a light transmission region through which exposure light with a predetermined wavelength transmits, a semi-transmission region having an optical characteristic of 180-degree phase shift and a light shielding region shielding exposure light. The semi-transmission region has a width set so as to be larger as a distance from the semi-transmission region to the light shielding region becomes short with respect to a region in which the semi-transmission region, the light transmission region and the light shielding region are sequentially formed outward from an exposure light passing region side. The width of the semi-transmission region is set so as to be smaller as the distance becomes long.
